Hardware requirements for SDXL on A1111? (lemmy.ml)

What are the hardware requirements to run SDXL?

In particular, how much VRAM is required?

This is assuming A1111 and not using --lowvram or --medvram.

3070 8gb vram, 16gb ram

In confy About 16-17sec to do everything at 1024x1024 with 20steps and 5 refiner.

A1111 About the same, using batch of 4 and then using batch img2img refining. Just more clicks without extensions etc as getting the same it/s between confy and a1111 - - medvram

I am using a 3070 8gb FTW, and 32gb ddr5....I have yet to get SDXL to even generate without an error yet. I assumed it was my hardware.

Nah, auto1111 seriously struggles with SDXL for me. But comfy manages to do it without issue.

I tried ComyfyUI last night - but, unless I am just missing something, I couln't get past the workflow screen. Thanks for the tip, I will keep tinkering with things.

I tried InvokeAI, but was having the same problem. I got the safetensor directly from Stability AI's hugging face page - so I have to be doing something wrong...3 different UIs and I couldn't get any to work. I am losing my technical aptitude :)

The best thing with comfy is you can drag a PNG image that was generated by it and it will replicate the workflow nodes. They have some images on their GitHub for examples
